DRIER.

Specification of Letters Iatent.

Patented Apr. 27, 1915.

To all whom it may concern:

Be it known that I, DANIEL M. COOPER, of Rochester, in the county of Monroe and State of New York, have invented certain new and useful/Improvements in Driers; and I do hereby declare the following to be a full, clear, and exact description of the same, reference being bad to the accompanying drawings, forming a part of this specification, and to the reference-numerals marked thereon.

My invention relates to driers, and more particularly to that class of machines embodying a rotating holder and means for discharging a current of heated air through the holder, such as are employed, in laundry drying plantsand for similar purposes, and it has for its object to provide a simple construction involving a novel arrangement of parts by whichthe work may be performed quickly and efliciently.

A further object of my invention consists in the provision of a machine that is adaptedto be converted from a vacuum operating drier into a pressure operating drier or vice versa according to the desire of the user.

T 0 these and other ends the invention consists in certain improvements and combinations of parts all as will be hereinafter more fully described, the novel features being pointed out in the. claims at the end of the specification.

In the drawings: Figure 1 1s a view 1n end elevation of a machine constructed in ac-.

cordance with a preferred embodiment of my invention; Fig. 2 is an elevation'of the opposite end of the machine; Fig. 3 is a rear elevation; Fig. 4 is a longitudinal vertical sectional view; Fig. 5 is a transverse vertical sectional view; Fig. 6 is a sectional view on the line 66 of Fig. 5; Fig. 7 is a transverse vertical sectional view of the lower part of a machine, embodying a modifled-arrangement of my invention; and Fig. 8 is a sectional view on the line 8--8 of Fig. 7.

Similar reference numerals throughout the several figures indicate the same parts.

In the present embodiment, the casing, which is preferably formed of separable'sections, comprises an upper portion 1, lower portion 2, and a rear portion 3, which are suitablybolted together, and are constructed as shown in order to enable the machine to be more readily handled during transportation, preparatory to being assembled. Journaled within the casing is a rotary holder, preferably in the form of a perforate cylin der designated generally at 4 and-mounted in the bearings 5 at the opposite ends ofthe casing. 1

Arranged at the rear of the.casing in the portion 3 thereof, is a heating chamber which is separated from the front part of the machine by a partition 6, and contains a plurality of heating coils 7 adapted to receive steam or other heating medium, while 8 designates heating coils, disposed near the top of the casing and separated from the drying cylinder by means of the circular wall 9 which extends downwardly to a point substantially above the bottom of the casing as shown in Fig. 5.

10 is a passage way formed at the top of the casing and connecting the heating chamber with the rotating cylinder, the heated air being directed downwardly into-the cylinder by the curved partition 11 which extends from the top of the casing to a point immediately adjacent to the top of the vcylinder.

Arranged beneath the drying cylinder is means for effecting movement of the heated air, and to this end, there are preferably provided a pair of suctionfans 12 mounted on the shaft 13. The fans include casings 14 having outlets 15 connecting with the passage or conduit 16, the latter beingopen at one end and in communication with the atmosphere, as shownin Fig. 2.

' 17 designates anadditional passage conduit separated from the passage 16 by the inclined wall 18, the passage 17 being in' communication with the atmosphere and with the bottom of the heating chamber and separated from the front part of the casing by means of the wall 19.

In the operation of the machine, a partial vacuum is created within the drying cylinder, the air being drawn through the passage 17 to the bottom of the heating cham her, as shown by the arrows in F ig. 2 thence upwardly to. a point above the top of the drying cylinder, and from there downwardly, transversely of the cylinder and into the suction fans, from which it passes out through the conduit 16. Access may be had to the bottom of the casing through the hinged door 20.

21 designates a door leading to the dryingder, such as may happen in treating clothes that have been dry cleaned. The fans may be operated in any suitable manner as by shaft 13 by thebelt 25. The shaft 13 is provided with fast and loose pulleys, and 26 1s a belt shifter for moving the belt from one to the other. The drying cylinderor holder is operated by means of a motor 27 which is connected through a suitable train of gearing with a gear wheel 28 fixed upon a stub shaft 29 which is carried by the cylinder.

In some instances, it is preferred to employ a pressure of air through the drying cylinder instead of creating a vacuum by suction, and to this end, the machine is arranged so that it may readily be adapted to either one system or the other. When the heated air is to be forced through thedrying cylinder by pressure, the parts are arrange as shown in Figs. 7 and 8, the fancasings '30 being turned so as to communicate with passages 31 which lead to the bottom of the heating chamber.

'32 is a passage connecting the bottom of the cylinder with the atmosphere, and separated from the fans by means of the inclined wall 33.

34 is a partition connecting the wall 33 with the upwardly extending front wall 35, whereby the air isforced directly from the bottom of the cylinder into the passage 32.

' With this form of the invention, the air is drawn from the atmosphere first to the fans, and forced thence through the passages 31 to the heating chamber. It is then carried under pressure, upwardly to the top of the casing, and downwardly through the drying cylinder, being discharged at the bottom into the outlet passage 32. l

I claim as my invention: 1. The combination with a casing, of a holder journaled in the casing, a heating chamber arranged in the casing, and means disposed beneath the holder at'the forward part of the casing and connected with a source of air supply for effecting movement of air through the heating chamber, and through the holder in a direction transversely thereof.

2. The combination with a casing, of a holder journaled in the casing, a heating chamber arranged in rear of the holder, a source of air supply connected with the heating chamber, and means arranged beneath't h e Holder at the forward part of the casing for effecting movement of the heated air therethrough.

3. The combination with a casing, of a holder journaled in the casing, a heating chamber, and means arranged beneath the holder at the forward part of the casing for causing a current of air to pass successively through the heating chamber, and through the holder in a direction transversely thereof.
